Magnetoresistance scaling, disorder, `hot spots' and the origin of $T$-linear resistivity in BaFe${}_2$(As${}_{1-x}$P${}_x$)${}_2$

The scaling of $H$-linear magnetoresistance in field and temperature was measured in under-doped (x = 0.19) and optimally-doped (x=0.31)~BaFe${}_2$(As${}_{1-x}$P${}_x$)${}_2$. We analyze t…
